SPECIFICATION forming part of Letters Patent No. 279,101, dated June 5,1883.

Application tiled February E9, D383 (Model.)

To Lil whom, it 77mg/ concern:

Beit known that l, DANIEL MoPHnnsoN, of Caledonia, county ot'Livingston, and State ot' New York, have invented a new and usetulImprovement in Grain-Binders, of which the Afollowing is ai'ull, clear,and exact description, reference being had to the accompanying drawings,making part of this specification.

`My invention relates toa novel means i'or separating the gavel to bebound from the incoming grain, and `for taking up the slack in ltheband; to the means 'for taking the cord from the needle and carryingit into the notched cord-holding disk or wheel; to the means for liftingthe portions ot' the band extending' around the bundle down past theknetter, and between said knotter an d the cord-hol der above theknotter t'or throwing the cord over the head ofthe revolving knetter andtoi-.ming the loop, and to the means for. simultaneously lifting thecord-holder tor giving the necessary slack for forming the loop in theends ot' the band, to the means for imparting a backward throw to thecord-holder for carrying the cord properly into `the cord-grasping hookot' the knotter-head in the process ot' raising the cordholder t'orgiving the neeessz-iry slack to `i'orm the loop, and for actuating andguiding the vertical, movements ot.' the cord-holder carrier, wherebythe iirst movement ot' the latter in descending is in a vertical pathfor taking up the slack in the band, and avoiding the displacing of saidband until the latter has been grasped' by the knotted hook or jaw ot'the knetter and to the combination, with said cord-holder carrier andknetter, of a rotating` knife andloop-stripper, the movement of which isso timed relatively to those of the knotter, hook, and cord-holdercarrier as to cut the cord after the slack has been taken out of theknot,

. and the ends of the band have been grasped by the knetter-hook of theknetter; to the means for shitting the cord from one side to the otherot' the vibrating hook or arm which takes the cord from the needle andcarries it into the cord-holder, and to certain details of `constructionand arrangement hereinafter described.

In the accompanying drawings, Figure 1 represents an elevation ot' myimproved knotting mechanism, taken from the stubble side of the machine.Fig. 2 is a front elevation,

and Fig. 3 is a rear elevation, of the same. Fig. 4 represents avertical. longitudinal sec` tion in line with the shaft ot' the knetter.Fig. 5 is aside elevation ot' the knotter detached, with itsactuating-pinions and hollow shaft in section. Fi (i is a top plan viewot'the knotter, and Fig. 'T is a bottom view ot the same. Fig. 8 showsin perspective the upper end of the knetter-shaft standard, with its camfor actu` ating the knetter-hook. Fig. 9 isa rear elevation ot' thetoothed disk actuating the knotter, and Fig. 10 is a similar ele 7ationot' the toothed segment actuating the revolving knife andloop-discharger.

The mecliianism employed t'or actuating the knetter .is similar to thatdescribed in Letters 'Patent granted to me March 5, 1878, No.

ment imparted to it in a manner and by mechanism similar to thatdescribed in Letters Patent. granted to me January 4, 1881, No. 236,347,and these `features, therefore, need not be described in detail i'urtherthan is necessary to ex plain my l'nesent improvements and theirconnection with said parts.

A A represent uprights of the frame oi' the elevator, by means of whichthe grain is earried over the main drive-wheel to a conc-z ve receiveror binder-table on the outer side ot' said wheel, said frame andelevator, together with the reaping-machine to which they are connected,being ot' any usual or preferred construction.

B 3 representan upright rectangular frame, in whichthe binding mechanismis mounted or supported, said frame being suspended on the outer sideot' the drive-wheel upon pivots at a, and ai', connecting it at itsupper inner corners with the upper ends of the uprights A. and A ot' theelevator-frame, the arrangement being such that the binder-trame can beturned over upon the elevator for transportation or t'or passing throughnarrow gatesor passages. The lower and inner longitudinal timber, B',otcthe binder-frame has itsends extended to form stops b I, which restagainst the lower ends of the uprights A and A', and serve to preventsaid frainei'rom swinging inward beyond a proper working position whenin use. The upper part ot' the frame B B `is provided with. suitablebearings for the mechanism through which an orbital movement is im?200,868, andthe needle has an orbital move IOO parted to the needle C,which movement and mechanism, being similar to that described in mypatent of January +L, 1881 above referred to, need not be heredescribed. To the upper end of this needle is pivoted a pendent rod, C,forming a grain-separator and cord take-up for separating from the gavelto be bound and crowding backward therefrom the grain coming into theconcave receiver behind the needle after thelatter has passed downthrough the grain for carrying the cord to the knotter, and also fortaking up the slack in said cord. rlhis rod C rests against the rearface of the needle C, 4its lower end by preference resting in a groovein the lower end of said needle in such manner as to adapt both to passdown through the grain together and prevent the grain from gettingbetween them. The cord or other band material passes from a spoolarranged on the inner side of the frame B through an eye, c, intheneedle, thence through an eye, a', in the point ofthe take-up rod C andback through an eye at c in the point of the needle Y (l, and thence tothe cord-holder underneath the grain-receptacle, hereinafter described.Upon a transverse bar, B2, of the frame B, at or near the center of itslength, is secured a stop-pin or standard, b, and the separatingrod C isprovided on its side, near its upper end, with a pin, c, which, as theneedle is carried downward and outward for carrying the,

cord to the cord-holder, comes in contact with the stop b', and serves,as the outward movement ofthe needle (l is continued, to impart apositive movement to the lower end of the rod C for moving the incominggrain back or inward awa-y from the outwardly-moving needle, and alsofor taking up any slack inthe band". The rod C is retracted into itsformer position against the needle, when released from the stop b, by aspring, c, surrounding the pivot through which it is connected with theneedle. A. grooved cam or other suitable means maybe substituted for thestop and spring for imparting the movements described to the rod C.

D is an upright rectangular frame, in which the knotting devices andtheir actuating mechanisms are mounted, said frame being rigidly securedat its lower end to the outer longitudinal timber or flooring of frameB. This frame is provided with bearings for a longitudinaldriving-shaft, E, and at its upper endV with a vertical sleeve, B,forming a bea-ring for the tubular shaft F of the knetter, the innersolid shaft,.l having its bearings in the tubular shaft. rlhe shaft Eserves to actuate the binding mechanism, a-nd is geared to and actuatedfrom the main drive-wheel ofthe reaper in any suitable manner. Othershafts hereinafter described have also their bearings in suitable lugsor arms ofthe frame D.

Upon the shaft E is secured a cam and gear wheel, G, upon which areformed a number of toothed segments and a cam and pin or eccentric, forpurposes which will be explained.

- The frame D is provided with arms to form bearings for a short shaft,E, on which a spur gear or segment, G, engaging with and actuated from atoothed segment, g, on the wheel is secured, said shaft E being providedon its forward end with a crank-arm, e, the wristpin e of which enters ahorizontal slot, 71, in an arm of a sliding plate, H. This plate H isprovided also with upright slots h and h2, vertical in their lowerportions and inclined or curved outward from the knotter at their upperportions, through which slots the plate H is secured to the forwardstandard ofthe frame D by headed pins which permit the vertical andlateral or inward' and outward movement of the plateiH, actuated by thecrank-pin e and guided by the form" of the slots h and 112. The upperend ofthe plate H is provided at h?" with bearings for the horizontalshaft of a rocking finger, f, which projects inward within the path ofthe needle C. This projecting finger is made in angular or crank form,and its point is acted upon by an incline formed at c* on the side ofofthe needle, the point of the finger serving to takethe cord from theneedle, and then, being rocked toward the knocker by the latter, tocarry said cord to and into the cord-holding devices. The finger f,after it escapes from the needle, is retracted to its former position,

for adapting it to again seize the cord, by a c spring, fl, surroundingits shaftj".

rIhe/cord-holding device consists of a forked arm, if, formed upon orsecured to the upper end of plate H, at its inner edge, and a toothedcord-holding wheel and attached ratchet-disk, vi, mounted in bearings inthe fork of said arm. To thel forward face of the plate H is pivoted anarm, l, provided with a projecting pin, if, which is acted upon, once ineach revolution of the shaft E, by a cam or eccentric, E2, fast on saidshaft in front of the frame D. To the swinging end of the arm l ispivoted apawl, I', the outer or free end of which engages theratchet-disk fi, and serves to move or rotate said disk a distance equalto the length of one tooth of the cord-holding wheel at each throw ofthe pawl. rlhe pawl is retracted for repeating the operation by anysuitable arrangement of stop on the frame D, said stop acting on the pinf near the upper end of the throw of plate H. The rocking movement ofthecord-finger f described carries the cord in between the teeth ofthecord-holding wheel, and the movement of the latter, as described,carries said cord in between said wheel and the sides of IOO IIO

IZO

the forked arm 71,4, thereby grasping and holding said cord. In thismovement the portion of the cord grasped by said toothed wheel, and

bearings et The outer end of this` shaftE` is provided witha'rearwardly-projecting linger,

e, which overrides the cord-fingerf, and serves to carry the cord inwardtoward the knetter until it clears the .point of said finger, when thetensionon said cord draws it intoproper and the knetter, for a purposewhich will be explained.

L is a vertical rock-shaft mounted in suitable bearings inoutwardly-projecting arms of the frame D, and provided near its lowerend with an inwaidly-projecting arm, L, which is acted upon by a cam, l,on the wheel G, for rocking said shaft L. The shaft L has an ar-m, L, onits upper end, which, by the rocking movement of the shaft, serves tocarry the portions ofthe band lying between the cordholding wheel` landthe bundle in within reach of the cord grasping and looping hookon theknetter, as hereinafter explained.

M is an upright shaft mounted in suitable bearings on the rearstandardof the frame D, and provided near its lower end with abevelpinion, m, which projects through an opening or slot in the rearupright or standard of frame D, and engages with a beveled segment, fm?,on a plate or disk,M, fast on the shaft E, and which at each revolutionserves to impart a single revolution tothe pinion m and shaft M. Aplate, nl?, on the shaft M, below the pinion m,

`provided with a flattened surface on one side,

which rests against the adjacent face of the disk M/ in the intervalsbetween t-he action of Y the segment m on the pinion, serves to preventaccidental displacement of the pinion m and shaft M and to hold them inproper position to be acted upon by the segment m on itsnext round.

To the upper end of the shaft H is secured an arm, M2, of a lengthsufficient to enable it to reach over the knotter, moving in closeproximity thereto,.and provided at its outer swinging end with anangular extension, m, terminating at its lower end in a knife or cutter,mt, theofiice of which arm and cutter is to cut the cord andsimultaneously to slip the loop` otfthe jawsof the knetter and over theends of the cordgrasped by the knetter-hook, as will be eX- pl'ained.The arm mZ sweeps over theknott-er, and the pendent or angular extensionm thereof serves to support the knife fmt below the plane of said headand to bring said arm into proper relation to the hooks or jaws of saidrI heknott-er is composed of th ree parts-wiz.,

the cap part or head N, rigidly secured to the upper end of the innershaft, F', the cord grasping and looping hook N, rigidly secured to theouter tubular shaft, F, and a second or knotting hook, N2, pivoted toand revolving with `the grasping andlooping hook N,but adapted, throughits pivotal connection therewith,to receive a lateral independentvibrating Inovement for enabling it to grasp and hold the end portionsof the band to be drawn through the loop in forming the knot. The hookik is provided (see Fig. '7) at orvnear the center of its length (fromits pivot to its point) with an inwardly-proj ecting spur, yn, whichprevents the cord from being carried too far back between the hooks Nand N2. .The hook or pivoted jaw N2 is further provided on its heelextension, beyond its pivotal connection with the hook N, with a pendentpin carrying a friction-roller, i1', which works in a cani-groove formedvon the upper end of the sleeve-standard D. (bee Fig. S.) This cani isdoublewalled, consisting of an inner wall, p, crescentshaped andpartially surrounding the knottershafts, for acting upon thefriction-roller `u to close the hook N`` on the hook or j aw N', and anouter wall, p, on the sleeve-bearing D, opposite the part of leasteccentricity of the cam )9,for crowding said roller inward toward the knetter-shafts and opening the hook or jaw NL. This outer Vall, p, of thecam-groove is shown detached from the sleeve-standard D', and adapted tobe secured thereto by means of a screw or equivalent fastening passingthrough a perforated lugor car, p2, into said vone piece with thestandard or applied there- .to in any preferred manner. rlhe cap portionor h ead N of the knotter is partly cut away on one side, and has apendent lip or jaw at n,

is grasped, and is by preference made convex on its upper face tofacilitate the forming and clearance ofthe loop.

Motion is imparted to the knetter by means of beveled pinions F`t and F3on the lower end of its shafts F and F, respectively, engaging withtoothed segments on the wheel G, as follows, viz: at g a short segmentof sufficient' less) to the pinion F2, shaft F, and hook or jaw forgrasping the two strands ofthe cord reaching from the holder around thebundle; a long ofthe teeth of segment g', for actuating both .pinionsF'Z and F simultaneously and impartvling three-quarters of a revolution(more. or

its cap or head N for carrying forward the j aw al and opening the hookN for releasing the cord and leaving the hook N open preparatory toforming a new loop. The concave receiver or table which receives thegrain from the elevator and in which the grain is bound will have N foradapting it to close against the jaw of,

segment at 92, with the teeth of double the widthV IOO sleeve-standardat b2,- but it may be formed in between which and the hook or j aw N thecord length to give a quarter-revolution (more or 1 2 5` less) to theent-ireknotter for forming the loop in the cord, and another shortsegment at g3 for giving a quarter-revolution to the shaft F andnecessary slack for forming the loop.

Qver and above the knetter.

a transverse slot formed in it, permitting the passage of the needle in.carrying the cord around the grain therein to the cord grasping andholding disk or wheel.

The operation is as follows: Supposing one end of the cord to be held inproper position by the cord-holding wheel, and the cord by the orbitalmovement of the needle to have been carried around the grain in theconcave receptacle, the rod C' and the cord-finger f, acting ashereinbefore described, the former for separating the grain and drawingthe cord tightly around the bundle, and the latter for picking the cordoff the needle and carrying it into the cord-holding wheel, bytherotation of which it is seized, as explained. Thus the two ends of theband surrounding the bundle in the concave receptacle are held by saidwheel. At this instant the arm L? is vibrated to carry the portions ofsaid cord extending between the concave and the cord -holding wheel towithin the sweep of the hoeklor jaw N', which is new carried through aquarter of a revolution by the action ofthe segment g' on the pinion F2,causing the cord to be grasped by the knetter between said hook and thejaw u2 of the cap or head N. At this instant, and in the interval ofrest given to the knetter, due to the space on wheel G between thesegments g' and g2, the curved arm k2, underlying the cord between theknetter and the cordholding wheel, is lifted by the action of the pin k"for raising that portion ofthe cord lying between the holder and knetterand throwing it At this point, the double-width segment y" havingreached the knetter-shaft pinion, the knetter is started on a movementof three-quarters of a revolution, more or less, the cord-holding wheelholdin g the ends of the band having in the meantiine been liftedthrough the action of the crank-pin e' on the plate H for supplying theAs the knetter begins its movement described the hook or jaw N2 isopened by the action of the cam-wall p', and the cord-holding wheelbegins its downward movement in a vertical path for drawing the looptight, and` at the same time holding the cord extending from over thecap or head N in position to be' grasped between the hook N2 and thehook N' before the knetter' completes its three-quarter revolutionreferred to, and said hook is closed upon the cord by the action of theinner wall, p, of the cam thereon. The downward movement of thecord-holder is first in a direct vertical path, due to the form f theslots h' and h2, to avoid V.drawing the cord out from between the jawsor hooks N' andN2 in taking up the slack prior to the closing of saidjaws orl hooks one on the other. At or about the instant the jaws N'- N2have closed firmly on the cord the segment g3 acts on the pinion F3 andshaft F', carrying forward the jaw vn2 a quarter-revolution, opening thehook N', and at the same time, the arm k2 having been released from theaction of the pin l5- and removed out of the path of the arm M2, 'thelatter is caused to rotate, carrying the knife m, the latter cutting thecord below the plane of the knetter and between said knetter and thecord-holding wheel, the pendent arm, to which the knife m* is attached,at the same instant slipping the loop over the ends or points of thehooks N' and N2, and over the ends of the band grasped and held betweensaid hooks, vas explained, and which are thus drawnthrough the loop,forming the knot.

Having now described my invention, what l claim as new isy l. Thecombination, with the needle, of a combined vibrating grain-separatorand cordtake-up rod pivoted to and moving with said needle, and meansfor intercepting the rod, so that the continued forward movement of thevneedle shall impart a positive backward movement to the swinging end ofsaid take-up rod, substantially as and for the purpose described.
